Why Do Asphalt Shingles Curl?

Curling roof shingles are quite obvious, and they significantly impact how your roofing looks. But more than their effect on your roof’s aesthetic appeal, they can also lead to serious problems and prevent your roofing system from performing at optimal level.

Dior Construction, one of the top residential roofing contractors in the area, discusses shingle curling and how it differs from other kinds of shingle wear.

What is Shingle Curling?

Shingle curling occurs on organic-mat or fiberglass-mat asphalt roof shingles. It can usually be found at the corners of a shingle tab, and it’s often considered a sign of normal wear among old roofs. If this is the case, you’ll have to replace your worn roof with a new one.

However, if curling happens in a relatively new roof, it may be an indication of an underlying moisture problem or roof vent issue. Sometimes curling can also be the result of shoddy installation. Call in a residential roof repair expert to know the root cause.

Shingle Curling Patterns

It’s a common mistake to use the terms “curling”, “cupping” and “fishmouthing” interchangeably. For some, getting it wrong doesn’t seem like a big deal. However, you need to know the distinction between the different patterns of shingle wear in order to treat the problem correctly.

Cupping is typically characterized by uplifted shingle perimeters and a concave, or “cupped,” center. Curling occurs at the individual shingle or shingle tab corners, while fishmouthing appears as an upward curve in the center of a shingle tab.

At first, these differences can be confusing, especially to the untrained eye. That’s why you should have a qualified professional inspect your roof.
